自定义 JSON 反序列化程序

我想创建一个自定义的JSON反序列化程序，可以将下面的json映射到C#类，任何建议，帮助或指向相关资源的指针将不胜感激。谢谢

{   
   "PersonId": "XXXXXXXXXXXXXX",
   "Name": "XXXXXXXX",  
   "HobbiesCollection":
        {"Hobby":
            [
                {
                    "type": "RUNNING",
                    "id": 44,
                    "description": "sprinting and sprinting?"
                },
                {
                    "type": "RUNNING",
                    "id": 45,
                    "description": "jogging and jogging"
                }
            ]
        }   
}

public class OtherStuff
{
    public OtherStuff(IList<Hobby> hobbyList)
    {            
        HobbyList = hobbyList;
    }

    public IList<Hobby> HobbyList
    {
        get;
        private set;
    }
}
